Thanks everyone for your help. I just ordered some new slant feet from Sew Classic last week, but looks like I need to put in another order for bobbins. The ones I just bought I ordered through Nancy's Notions...they are probably similar to the others some of you have had that didn't work. I want to learn to FMQ on the 301, so I'll want to fill several bobbins at once so I can keep going and not stop too often to rewind them. At least I have 3 so I can get started.
